The digestive tract's immune system is often referred to as gut-associated lymphoid tissue (GALT)
and works to protect the body from invasion. GALT is an example of mucosa-associated lymphoid tissue
About 70% of the body's immune system
is found in the digestive tract
. The GALT is made up of several types of lymphoid tissue
that produce and store immune cells, such as T and B lymphocytes, that carry out attacks and defend against pathogens
New research indicates that GALT may continue to be a major site of HIV activity, even if drug treatment has reduced HIV count in the peripheral blood.
Lymphoid tissue in the gut is comprised of the following :
- - "Digestive System: Alimentary Canal: colon, taenia coli"
- - "Digestive System: Alimentary Canal: esophageal/stomach junction"
